Warning! This Nailer has a Sequential Trip safety mechanism. With the trigger pulled,
the unit will fire each time the nose of the Nailer contacts a surface. This Nailer is not
suited for single shot work. Vibration and bouncing and delayed finger pressure will
commonly result in the unit double firing.
Testing the Sequential Trip Safety Mechanism (Always test while using scrap material.)
1. The Nailer should not fire if the nose is not depressed against the workpiece.
2. Make sure the tool is disconnected from the power supply.
3. Empty the magazine of nails.
4. Check that the Trigger (31) and the nose of the tool, moves freely, without sticking.
5. Connect the air supply to the tool at the Air Inlet (33) and set at the recommended 60-115
PSI, and not over the maximum 130 PSI.
6. Test the tool by depressing the nose of the tool against the workpiece without pulling the
Trigger (31). The tool must not cycle (fire). If it cycles (fires), stop immediately and take the
tool to an qualified service technician for repair.
7. Hold the tool away or off of the workpiece. The nose of the tool should return to its original
position. Squeeze the Trigger (31). The tool should not cycle (fire). If it cycles (fires), stop
immediately and take the tool to an authorized service technician.
